Description
Technical field
The utility model relates to vibration damping equipment, particularly a kind of pneumatic spring.
Background technique
Pneumatic spring is realized a kind of spring assembly of damping effect for the compressibility of utilizing air.In the modern railway transportation technology of high speed development, pneumatic spring is widely used.
The topmost parts of pneumatic spring have upper cover plate, but the rubber bag tank of free deformation, supporting base, the rubber elasticity parts that formed by rubber and metal.The Main Function of pneumatic spring is connection body and bogie, supports car body and passenger weight, the substantially horizontal of vehicle operating and the distortion of above-below direction, buffering vibration noise decrease etc. is provided.
Pneumatic spring has two kinds of utilization states in vehicle: the one, and normal inflated condition, gas-flow closure carrying in rubber bag tank; The 2nd, emergent air deflating state, do not have air in rubber bag tank, by the rubber elasticity parts, carried.
In the technical development process, pneumatic spring has been proposed to more and more stricter requirement, need to take into account little, the requirements such as quality is light, displacement capacity is strong, good stability, above-below direction restriction deflection that take up room simultaneously.
Existing product generally has two kinds of structures: the one, and the structure of little bent capsule and laminated spring, as shown in Figure 1, there is it lightweight, the advantage that lateral displacement is larger, but lateral stability is very poor, during emergent air deflating state, the rigidity of above-below direction is very large, and vehicle derailing has a big risk, and is difficult to restriction vehicle deflection; The 2nd, Daqu capsule and secondary spring structure, as shown in Figure 2, its lateral displacement ability is larger, and comfort level is better, but the product structure complexity, weight is larger, and height and profile spatial requirement are large.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of pneumatic spring, and it simultaneously takies little, the functions such as quality is light, displacement capacity is strong, good stability and restriction deflection in implementation space.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: described pneumatic spring comprises upper cover plate, undersetting, rubber bag tank, rubber elasticity parts, described rubber bag tank connects upper cover plate and rubber elasticity parts, described rubber elasticity parts are hollow structure, by rubber and metal, formed, the hollow space of rubber elasticity parts is inner chamber; Undersetting is arranged on the rubber elasticity parts and is positioned at rubber bag tank inside, the undersetting structure is polymorphic structure, undersetting is shaped as " M " shape or " U " shape, and with strengthening gusset more than three or three to meet requirement of strength, extend under the undersetting intermediate portion in the inner chamber of rubber elasticity parts, and have through hole to be communicated with the inner chamber of rubber bag tank and rubber elasticity parts.
Described rubber elasticity parts intermediate portion is empty, and described rubber elasticity parts comprise base plate and be connected to the metal column on base plate, and metal column stretches into the inner chamber of rubber elasticity parts, and the metal column top is with the lifting screw.The integrative-structure that described base plate and metal column are employing cast inblock shaping or employing are welded or are adopted and be threaded.Described base plate has two layers or more sheet metal, and described sheet metal diameter from top to bottom reduces successively.The rubber part of described rubber elasticity parts has one deck or two layers of metal partion (metp).Described base plate intermediate portion is empty, and described base plate is with the base plate gusset.Leave gap between described upper cover plate and undersetting and between undersetting and metal column, the height of described undersetting and metal column can be regulated.
Compared with prior art, the structure of rubber bag tank of the present utility model and described rubber elasticity parts, take up room little.Product structure is simple, and quality is light.Displacement capacity is strong, good stability.Can limit deflection in inflation and air deflating state.
The accompanying drawing explanation
Fig. 1 is the structural representation of little bent capsule and laminated spring;
Fig. 2 is Daqu capsule and secondary spring structural representation;
Fig. 3 is the utility model pneumatic spring structural representation.
In figure: 1, upper cover plate; 2, undersetting; 3, rubber bag tank; 4, rubber elasticity parts; 4a, base plate gusset; 4b, metal column; 4c, base plate.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As seen from Figure 3, described pneumatic spring comprises upper cover plate 1, undersetting 2, rubber bag tank 3, rubber elasticity parts 4, but the rubber bag tank 3 by free deformation connects upper cover plate 1 and rubber elasticity parts 4, rubber elasticity parts 4 are hollow structure, by rubber and metal, formed, the rubber part of rubber elasticity parts has two layers of metal partion (metp).Undersetting 2 is arranged on rubber elasticity parts 4 and is positioned at rubber bag tank 3 inside, undersetting 2 is " M " shape (also can adopt " U " shape), and can strengthen gusset to meet requirement of strength with being no less than 3, its structure is polymorphic structure, extend under intermediate portion in the inner chamber of rubber elasticity parts 4, and have through hole to be communicated with the inner chamber of rubber bag tank 3 and rubber elasticity parts 4.Rubber elasticity parts 4 can all can produce moderate finite deformation in upper and lower, substantially horizontal, and the ability of substantially horizontal large deformation plays larger help to the deformability of pneumatic spring.Rubber elasticity parts 4 inner chambers have metal column 4b to sink too much to prevent the pneumatic spring overall height, play the effect of above-below direction backstop, and the base plate 4c of metal column 4b and rubber elasticity parts 4 is structure as a whole, and has guaranteed intensity and relative position.Screw is used with lifting in metal column 4b top, facilitates the pneumatic spring carrying.Metal column 4b and special-shaped undersetting 2 cooperatings play the above-below direction backstop action.Adjust gap set between upper cover plate 1 and undersetting 2 and undersetting 2 and metal column 4b by the height of adjusting undersetting 2 and metal column 4b.From the metal column 4b cast inblock base plate 4c together highly also adjustable setting height(from bottom) demand to realize that pneumatic spring is different, base plate 4c hollow belt base plate gusset 4a, not only meet requirement of strength but also reduce air spring system weight.Another base plate 4c has the sheet metal up and down that is no less than 2 layers, upper and lower sheet metal diameter difference, upper board diameter is greater than lower board diameter, and lower board diameter meets the interface size requirement of installing with bogie, upper plate with the support rubber elastic member, guarantees the stability of a system in radial expansion.
Described metal column also can adopt welding or adopt with metal base plate and be threaded.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all being included in protection domain of the present utility model.
